United States Patent SLIDABLY ADJUSTABLE EXTENDER PLATE FOR SUPPORT BRACKETS James J. Folker, Springfield, Ill.

Application February 23, 1954, Serial No. 411,685

1 Claim. (Cl. 248-265) My invention is a slidably adjustable extender plate for support brackets, wherein, curtain rods, draperies, towel hangers and the like may be removably attached thereto for widening or narrowing the sidewise dimension of the same when in use.

This extender bar is slidably mounted upon a bracket that is fastened to the wall frame in position to permit the extender bar to be selectively adjusted slidably to the desired width.

A bracket is mounted upon the extender bar at its outer ends to hold a curtain or drapery or towel rod in a fixed position relative to the extender bar.

Thus a particular purpose of my invention is to provide a sturdy, serviceable, practical and economical extender plate adapted to ofier means for operatively manipulating an adjustable support for such above mentioned items making it operable to spread a curtain or drape and the like wider than the window casing, when desired, and do so in a graceful manner to leave it neat at all times for the interior decoration of a home and the like.

My invention is described herein and has been defined in the drawings, wherein:

Fig. 1 is a perspective of my extender plate per se.

Fig. 2 is a front view of the same.

Fig. 3 is a perspective of a resilient supporting clamp for the extender plate of Fig. 1.

Fig. 4 is an end view of my assembled extender plate.

Fig. 5 is an opposite end view of the same.

The outstanding features of novelty in my extender plate will be readily observed in a careful study of its design and construction.

Another recognition of its merits may be found in the fact that this invention has received a wide and growing public acceptance without any advertising other than showing it to housewives and merchants.

I shall herein describe this invention as I make reference to its service as an extender plate for support of common curtain rod brackets, and traverse rods.

I believe that I am advancing a new teaching in this art, wherein, I am providing an elongated extender plate 1 having a top flange 2 and a bottom flange 3; while uniformly spaced upright slots or recesses 4 are punched into the top surface 5 of said extender plate 1.

When mounting these extender plates 1 on a window frame, not shown, then supporting bracket 6 with its upper channel 7 and lower channel 8 is first secured to a window frame and the like by entering screws into screw holes 9, 10 and 11 in position so that spring member 12 is held in place by the screw 13 that fits into the hole of spring 12 that registers with hole 11 in plate 6.

With this supporting bracket 6 thus mounted on a window frame then the resilient spring member 12 tends to press its central stop member rib 14 into the space between slots or recesses 4 of extender plate 1 thus providing means for holding the extender plate 1 more firmly in its selected positions of slidable adjustment.

These recesses 4 are pressed into the front surface of extender plate 1 thus protruding in the back (see No. 4 in Fig. 4).

Having thus described my invention, what I claim is:

A support assembly for curtains or the like comprising a bracket for attachment to a supporting surface and a mounting plate adjustably carried by said bracket, said bracket including a flat central plate, inturned top and bottom edges on said central plate thereby forming generally horizontal guide channels on the upper and lower edges of the central plate with the guide channels facing each other, said central plate having apertures therein for receiving fasteners for mounting the bracket on a vertical supporting surface, said central plate and guide channels being of one-piece construction, a leaf spring extending longitudinally of the central plate in spaced parallel relation to the guide channels with the ends there of spaced from the ends of the central plate, a fastener securing one end of the spring to the surface of the central plate, said spring being arcuately bowed with the other end movably engaging the surface of the central plate and the midportion of the spring being spaced from the surface of the central plate, the midportion of said spring including a transverse rib projecting from the surface thereof, said mounting plate including an elongated channel-shaped member having a bight portion and legs extending perpendicularly therefrom, the outer edge of each leg including an outwardly extending flange slidably engaged in the guide channels on the bracket, said channel-shaped member being longer than the bracket with the bight portion having a plurality of longitudinally spaced transverse projections on the inner surface thereof, said rib on the spring frictionally engaging the inner surface of the bight portion with the projections providing frictional stops for releasably retaining the mounting plate in adjusted position longitudinally of the bracket, one end of said bight portion having an extension plate coplanar therewith and having side edges coextensive with the edges of the flanges, the transition portion of the flanges and legs connected with the extension plate forming stops for limiting the sliding movement of the mounting plate in one direction, the end edge of said extension plate having a downturned flange having apertures therein for attachment of a supported article, said extension plate including a first pair of slots disposed along the longitudinal axis of the mounting plate and being disposed in longitudinal alignment and a second pair of slots arranged in transverse alignment with the longitudinal axis of the second pair of slots being perpendicular to the longitudinal axis of the mounting plate, said slots adapted to receive fasteners for mounting various types of curtain brackets or the like.
